ISO 14649-111:2010

Industrial automation systems and integration — Physical device control — Data model for computerized numerical controllers — Part 111: Tools for milling machines

ISO 14649-111:2010 specifies the data elements describing cutting tool data for milling machine tools and machining centres, which work together with the process data for milling machine tools and machining centres specified in ISO 14649-11. They can be used as criteria for selecting one of several operations; they do not describe complete information on a particular tool. Therefore, leaving out optional attributes gives the controller more freedom to select from a larger set of tools. ISO 14649-111:2010 also specifies the information to be provided in the tool set-up sheet: tool identifier; tool type; tool geometry; application-dependent expected tool life. The following data types are outside its scope: normative tool life; tool location in the tool changer; adaptive items also know as tool holders or tool clamping devices; tools for other technologies, such as turning, grinding and electrical discharge machining (EDM). ISO 14649-111:2010 uses the EXPRESS language as specified in ISO 10303-11.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14649-111 was prepared by Technical Committee ISO/TC 184, Automation systems and integration,
Subcommittee SC 1, Physical device control.
ISO 14649 consists of the following parts, under the general title Industrial automation systems and
integration — Physical device control — Data model for computerized numerical controllers:
⎯ Part 1: Overview and fundamental principles
⎯ Part 10: General process data
⎯ Part 11: Process data for milling
⎯ Part 12: Process data for turning
⎯ Part 111: Tools for milling machines
⎯ Part 121: Tools for turning machines
The following parts are under preparation:
⎯ Part 13: Process data for wire-EDM
⎯ Part 14: Process data for sink-EDM
Machine tool data model for general manufacturing processes is to form the subject of a future Part 110.
Gaps in the numbering were left to allow further additions. ISO 14649-10 is the ISO 10303 application
reference model (ARM) for process-independent data. ISO 10303 ARMs for specific technologies are added
after Part 10.
ISO 14649 is harmonized with ISO 10303 in the common field of product data over the whole life cycle.
ISO 14649-1:2003, Figure 1, shows the different fields of standardization between ISO 14649, ISO 10303 and
CNC manufacturers with respect to implementation and software development.

Introduction
Modern manufacturing enterprises are built from facilities spread around the globe, which contain equipment
from hundreds of different manufacturers. Immense volumes of product information will be transferred
between the various facilities and machines. Today's digital communications standards have solved the
problem of reliably transferring information across global networks. For mechanical parts, the description of
product data has been standardized by ISO 10303. This leads to the possibility of using standard data
throughout the entire process chain in the manufacturing enterprise. Impediments to realizing this principle are
the data formats used at the machine level. Most computer numerical control (CNC) machines are
programmed in the ISO 6983 “G and M code” language. Programs are typically generated by computer-aided
manufacturing (CAM) systems that use computer-aided design (CAD) information. However, ISO 6983 limits
program portability for three reasons. First, the language focuses on programming the tool centre path with
respect to machine axes, rather than the machining process with respect to the part. Second, ISO 6983
defines the syntax of program statements, but in most cases leaves the semantics ambiguous. Third, vendors
usually supplement the language with extensions that are not covered in the limited scope of ISO 6983.
ISO 14649 is a new model of data transfer between CAD/CAM systems and CNC machines, which replaces
ISO 6983. It remedies the shortcomings of ISO 6983 by specifying machining processes rather than machine
tool motion, using the object-oriented concept of Workingsteps. Workingsteps correspond to high-level
machining features and associated process parameters. CNCs are responsible for translating Workingsteps to
axis motion and tool operation. A major benefit of ISO 14649 is its use of existing data models from
ISO 10303. As ISO 14649 provides a comprehensive model of the manufacturing process, it can also be used
as the basis for a bi- and multi-directional data exchange between all other information technology systems.
ISO 14649 represents an object-oriented, information- and context-preserving approach for NC (numerical
control) programming that supersedes data reduction to simple switching instructions or linear and circular
movements. As it is object- and feature-oriented and describes the machining operations executed on the
workpiece, and not machine-dependent axis motions, it will be run on different machine tools or controllers.
This compatibility will spare all data adaptations by postprocessors, if the new data model is correctly
implemented on the NC controllers. If old NC programs in ISO 6983 are to be used on such controllers, it is
necessary that the corresponding interpreters be able to process the different NC program types in parallel.
ISO TC 184/SC 1/WG 7 envisions a gradual evolution from ISO 6983 programming to portable feature-based
programming. Early adopters of ISO 14649 will certainly support data input of legacy “G and M codes”
manually or through programs, just as modern controllers support both command-line interfaces and graphical
user interfaces. This will likely be made easier as open-architecture controllers become more prevalent.
Therefore, ISO 14649 does not include legacy program statements, which would otherwise dilute the
effectiveness of ISO 14649.
